Correlations between earthquakes and anomalous particle bursts from SAMPEX/PET satellite observations.
No full textIn the last decades, a possible influence of electromagnetic fields of seismic origin in the ionosphere–magnetosphere
transition region has been reported in the literature. In recent years, a few space experiments also revealed anomalous
bursts of charged particles precipitating from the lower boundary of the inner radiation belt. They were thought to be
caused by low-frequency seismo-electromagnetic emissions. A recent study [Aleksandrin et al., 2003. Annales
Geophysicae 21, 597–602] seems to confirm that these particle bursts have a short-term preseismic character. The
particle longitudinal drift should enhance the detectability of preseismic particle bursts, thus magnifying their
importance in earthquake prediction studies. This paper takes into consideration the method introduced by
Aleksandrin et al. (2003) to carry out a deeper investigation on the subject. In this sense, a method for the temporal
correlation between continental earthquakes with MX5:0 and anomalous particle bursts collected by the PET-
SAMPEX satellite mission is critically investigated and presented here. Several constraints and cuts have been applied
to data in order to exclude, from the correlation, charged particles collected inside the SAA region and/or during
ionospheric and magnetospheric perturbations caused by non-seismic sources. After the data have been detrended by
these effects, a short-term seismic precursor of 4 h is observed in the histogram of the time difference between the time
occurrence of earthquakes and that of particle burst events. The best correlation is obtained only when considering
high-energy electrons (EX4 MeV) with pitch angles near the loss cone. Such a result confirms previous ones but also
points out the importance of an ad hoc method of analysis. Results suggest the importance of coordinated and
simultaneous ground-based and space investigations specifically dedicated to the subject. Also, a deeper investigation
based on particle data prepared and analyzed as carefully as possible is requested to understand the physical
mechanisms underlying the phenomenon under study

I Think I Am Philip K. Dick
No full textFor years, noted writer Laurence A. Rickels often found himself compared to novelist Philip K. Dickthough in fact Rickels had never read any of the science fiction writers work. When he finally read his first Philip K. Dick novel, while researching for his recent book The Devil Notebooks , it prompted a prolonged immersion in Dicks writing as well as a recognition of Rickelss own long-documented intellectual pursuits. The result of this engagement is I Think I Am: Philip K. Dick , a profound thought experiment that charts the wide relevance of the pulp sci-fi author and paranoid visionary. I Think I Am: Philip K. Dick explores the science fiction authors meditations on psychic reality and psychosis, Christian mysticism, Eastern religion, and modern spiritualism. Covering all of Dicks science fiction, Rickels corrects the lack of scholarly interest in the legendary Californian author and, ultimately, makes a compelling case for the philosophical and psychoanalytic significance of Philip K. Dicks popular and influential science fiction.Intro -- Contents -- Introjection -- Part I -- Endopsychic Allegories -- Schreber Guardian -- Belief System Surveillance -- Part II -- Deeper Problems -- Veil of Tears -- Go West -- Dick Manfred -- Timing -- Glimmung -- Part III -- Spiritualism Analogy -- Imitating the Dead -- Indexical Layer -- Ilse -- Hammers and Things -- Crucifictions -- Over There -- Martyrology -- Can't Live, Can't Live -- Lola -- Umwelt, Mitwelt, and Eigenwelt -- Outer Race -- The German Introject -- Part IV -- Materialism, Idealism, and Cybernetics -- Startling Stories -- A Couple of Years -- Android Empathy -- Homunculus and Robot -- ALL OF YOU ARE DEAD.

Inner radiation belt source of helium and heavy hydrogen isotopes
No full textNuclear interactions between inner zone protons and atoms in the upper atmosphere provide the main source of energetic H and He isotopes nuclei in the radiation belt. This paper reports on the specified calculations of these isotope intensities using various inner zone proton intensity models (AP-8 and SAMPEX/PET PSB97), the atmosphere drift-averaged composition and density model MSIS-90, and cross-sections of the interaction processes from the GNASH nuclear model code. To calculate drift-averaged densities and energy losses of secondaries, the particles were tracked in the geomagnetic field (modelled through IGRF-95) by integrating numerically the equation of the motion. The calculations take into account the kinematics of nuclear interactions along the whole trajectory of trapped proton. The comparison with new data obtained from the experiments on board RESURS-04 and MITA satellites and with data from SAMPEX and CRRES satellites taken during different phases of solar activity shows that the upper atmosphere is a sufficient source for inner zone helium and heavy hydrogen isotopes. The calculation results are energy spectra and angular distributions of light nuclear isotopes in the inner radiation belt that may be used to develop helium inner radiation belt model and to evaluate their contribution to SEU (single event upset) rates.

The AM Canum Venaticorum binary SDSS J173047.59+554518.5
No full textThe AM Canum Venaticorum (AM CVn) binaries are a rare group of hydrogen-deficient, ultrashort period, mass-transferring white dwarf binaries and are possible progenitors of Type Ia supernovae. We present time-resolved spectroscopy of the recently discovered AM CVn binary SDSS J173047.59+554518.5. The average spectrum shows strong double-peaked helium emission lines, as well as a variety of metal lines, including neon; this is the second detection of neon in an AM CVn binary, after the much brighter system GP Com. We detect no calcium in the accretion disc, a puzzling feature that has been noted in many of the longer period AM CVn binaries. We measure an orbital period, from the radial velocities of the emission lines, of 35.2 ± 0.2 min, confirming the ultracompact binary nature of the system. The emission lines seen in SDSS J1730 are very narrow, although double-peaked, implying a low-inclination, face-on accretion disc; using the measured velocities of the line peaks, we estimate i ≤ 11°. This low inclination makes SDSS J1730 an excellent system for the identification of emission lines
Freedom of choice or force of circumstance? : Eastern European sex-workers in the Republic of Cyprus ; paper for the conference 'Alltag der Globalisierung. Perspektiven einer transnationalen Anthropologie', January 16-18, 2003, Institute of Cultural Anthropology and European Ethnology, Johann Wolfgang Goethe University, Frankfurt am Main
No full textThis paper focuses on Eastern European migrants who, since the beginning of the 1990s, are entering the Republic Cyprus as “artistes”. This is a visa permit status as well as an euphemism for short-term work permits in the local sex industry. In addition to exploring the migrational experiences of these women and their living and working conditions in the Republic of Cyprus, the paper reconstructs, empirically and analyt ically, the connection between immigration and the local sex industry. Here, several categories of social actors and institutions in Cyprus are actively involved. The rhetoric of government representatives, entrepreneurs and clients in the sex business on the one hand is contrasted with the discourse of local NGO representatives concerned with immigrants’ rights on the other hand. The paper comes to the conclusion that all of these discursive positions ultimately do not do justice to the complex process of decisionmaking that women undergo who migrate into the sex industry. Either, freedom of choice is emphasized – such as by entrepreneurs and the government – or the domination of women – as in the public statements of the NGO. In order to analyze the ambivalent tension between freedom of choice and submission to force by which the women’s decision is characterized, the author employs Michel Foucault’s concept of governmentality, which describes forms of political regulation that use the individual’s freedom of action as an instrument to exercise power

An examination of author characteristics in national and regional criminology and criminal justice journals, 2008-2010: Are female scholars changing the nature of publishing in criminology and criminal justice?
No full textCriminology and criminal justice (CCJ) as an academic discipline has experienced an increase in the focus on various aspects of academic productivity in recent years. Much of the extant literature examining journal article authorship has focused on various measures of the publication productivity of specific authors but not on the characteristics of the authors themselves. The current study expands upon previous work by examining several author characteristics across different journal types and research methodologies, with a particular focus on how gender relates to these issues. The findings reveal several interesting differences with regard to gender, academic rank, and university affiliation. Among these findings is evidence that although males are more likely to author CCJ articles regardless of journal type, females are more likely to be lead authors in regional journal articles and more likely to publish with other female authors. Regional journals are also the publication outlet of choice for students and assistant professors in the beginning of their careers. The findings also provide evidence of important differences in author rank, academic affiliation, methodology, and publication outlet for articles authored by females.Journal ArticlePublishe
